    When his slipped did it do what mine is doing? Or did it just keep reving higher and go nowhere?

    The truck stop can adj. the clutch, it must be adj. to keep it from slipping, if you keep driving it you will need a new flywheel along with clutch, if you have clutch pedal does it have 1 or 2in. of free/play at top of pedal?

    It's only a 2 pedal. The Kw mechanic had said it's an auto adjusting clutch, but he didn't actually look at it, so may have been assuming. Disconnecting the battery didn't do anything, so it's def clutch. Heading to nearest shop now.
     
    magoo68 and baha Thank this.

    Ta mechanic checked the clutch, said it's more of a liquid torque converter. Can't be adjusted and can't see wear. Said there's no tranny shops around either... Sigh
